INTRODUCTION: Patients with ulcerative colitis (UC) regard rapid onset of action among the most important aspects of their treatment. We used the partial Mayo Clinic Score (pMCS) and component patient-reported subscores to assess the rapidity and sustainability of response to filgotinib, a once-daily, oral Janus kinase 1 preferential inhibitor, in adults with moderately to severely active UC in the phase 2b/3 SELECTION trial. The association between early symptomatic improvements and health-related quality of life (HRQoL) outcomes was also assessed. METHODS: In these post hoc analyses of the double-blinded, randomized, placebo-controlled 58-week SELECTION trial (NCT02914522), rectal bleeding and stool frequency diary data on days 1–15 and pMCS remission and response at multiple time points including weeks 10 and 58 were evaluated. HRQoL was assessed using the Inflammatory Bowel Disease Questionnaire at weeks 10 and 58. RESULTS: Filgotinib 200 mg relative to placebo improved rectal bleeding and stool frequency within 7 days ( P < 0.05). By week 2, greater proportions of filgotinib 200 mg-treated patients than placebo-treated patients achieved pMCS remission (biologic-naive, 15.1% vs 8.0%, P = 0.0410; biologic-experienced, 10.3% vs 4.2%, P = 0.0274). A similar treatment effect was observed at week 58 ( P < 0.0001). Day 7 rectal bleeding and stool frequency subscores were associated with the Mayo Clinic Score response at weeks 10 and 58. Patients in pMCS remission at weeks 10 and 58 had greater improvements in the Inflammatory Bowel Disease Questionnaire score than those not in pMCS remission. DISCUSSION: Filgotinib 200 mg daily resulted in rapid and sustained improvements in both UC symptoms and HRQoL.

Abstract Background and Aims Corticosteroid-free remission is an important treatment goal for patients with ulcerative colitis [UC]. The corticosteroid-sparing effects of filgotinib, an oral, Janus kinase 1 preferential inhibitor, were assessed in SELECTION, a placebo-controlled, phase 2b/3 trial in moderately to severely active UC. Methods These post hoc analyses assessed 1-, 3-, 6-, and 8-month rates of corticosteroid-free clinical remission at Week 58 and change in median daily prednisone-equivalent dose over time. A matching-adjusted indirect comparison [MAIC] of maintenance studies assessed corticosteroid-free remission with filgotinib 200 mg, intravenous vedolizumab, subcutaneous vedolizumab, and oral tofacitinib. Results The Maintenance Study full analysis set included 199 patients receiving filgotinib 200 mg and 98 receiving placebo. Among patients receiving corticosteroids at Maintenance Study baseline, at Week 58, 30.4%, 29.3%, 27.2%, and 21.7% receiving filgotinib had been in corticosteroid-free remission for ≥1, ≥3, ≥6, or ≥8 months, respectively, versus 6.4% receiving placebo across thresholds [p &lt;0.05]. Median daily prednisone-equivalent dose decreased from 17.5 mg/day to 10.0 mg/day with filgotinib treatment during the Maintenance Study. Based upon the MAIC, filgotinib was associated with greater likelihood of corticosteroid-free clinical remission versus intravenous vedolizumab (odds ratio [OR], 15.2; 95% confidence interval [CI], 1.6–139.9; p &lt;0.05]) and similar odds to subcutaneous vedolizumab [OR, 3.8; CI, 0.2–63.8; p = 0.36] in biologic-naïve patients, and similar odds to tofacitinib overall [OR, 2.0; 0.4–9.1; p = 0.39]. Conclusions Filgotinib 200 mg demonstrated corticosteroid-sparing effects and maintained corticosteroid-free clinical remission in patients with UC. MAIC results should be interpreted cautiously given the large CIs and differences in study design and patient populations. [ClinicalTrials.gov: NCT02914522].

Abstract Background Upadacitinib (UPA), an oral selective and reversible JAK inhibitor, demonstrated significantly greater efficacy compared with placebo (PBO) for induction of remission in patients with moderately to severely active ulcerative colitis (UC) in two phase 3 induction trials. Aims Evaluate safety and efficacy of 52 weeks of UPA 15 mg QD (UPA15) and 30mg QD (UPA30) compared to placebo in patients achieving clinical response following UPA 45 mg treatment in the induction trials. Methods The primary analysis (n=451) evaluated efficacy and safety of UPA15 and UPA30 compared to PBO as maintenance therapy. The primary endpoint was clinical remission via adapted Mayo score at wk 52. Ranked secondary endpoints included endoscopic improvement, maintenance of clinical remission, corticosteroid-free clinical remission, maintenance of endoscopic improvement, endoscopic remission, maintenance of clinical response and Histologic-endoscopic mucosal improvement (HEMI). Results Baseline characteristics were similar between all treatment groups. Both UPA15 and UPA30 met the primary endpoint, and all secondary endpoints. Significantly greater percentages of patients receiving UPA15 and UPA30 vs. PBO achieved clinical remission (42.3% and 51.7%, vs. 12.1%), endoscopic improvement (48.7% and 61.6%, vs. 14.5%), maintenance of clinical remission (59.2% and 69.7%, vs. 22.2%), corticosteroid-free clinical remission (57.1% and 68.0%, vs. 22.2%), maintenance of endoscopic improvement (61.6% and 69.5%, vs. 18.9%), endoscopic remission, (24.2% and 25.9%, vs. 5.6%) and HEMI (34.8% and 49.3%, vs. 11.8%) (p&lt;0.001 for all endpoints). UPA15 and UPA30 were both well-tolerated and no new safety signals were observed. Rates for serious adverse events (AEs) and AEs leading to treatment discontinuation were similar between UPA15 and UPA30 groups and lower compared to the PBO group. Most common AEs were nasopharyngitis and creatine phosphokinase elevation among UPA groups and UC exacerbation within the PBO group (30.2%). Herpes zoster was only reported in UPA groups (3.9%-4.1%). Similar rates of malignancy excluding NMSC were seen within all groups (0.7%-1.3%). MACE were only reported among patients receiving PBO (0.7%), while VTE were only found with UPA30 (1.3%). Conclusions In patients responding to UPA induction therapy, both UPA15 and UPA30 were safe and effective as maintenance treatment at 52 wk for all primary and secondary endpoints. Patients receiving UPA30 responded approximately 10% better for most endpoints compared to those receiving UPA15. Both doses were well-tolerated, with no new safety signals observed.

Abstract Background Health-related quality of life (HRQOL) is reduced in patients (pts) with ulcerative colitis (UC). We report on the HRQOL benefits of maintenance treatment with upadacitinib (UPA), a selective and reversible Janus kinase inhibitor, in pts with moderately to severely active UC in the Phase, 3 multicentre, randomised, double-blind U-ACHIEVE maintenance study (NCT02819635). Methods This study included a primary analysis of, 451 pts who achieved clinical response following treatment with UPA, 45 mg once daily (QD) in two replicate, 8-week induction studies, U-ACHIEVE induction, and U-ACCOMPLISH (NCT03653026). In U-ACHIEVE maintenance, pts from both induction studies were re-randomised, 1:1:1 to receive QD UPA, 15 mg, UPA, 30 mg, or PBO. HRQOL outcomes evaluated included the percent of pts reporting a clinically meaningful within-person change (MWPC) from induction baseline to Week, 0 (maintenance baseline) and Week, 52 (end of maintenance) in a broad range of HRQOL measures, including Inflammatory Bowel Disease Questionnaire (IBDQ), Work Productivity and Impairment Questionnaire (WPAI), Short Form, 36 (SF-36), European Quality of Life-5 Dimensions, 5 Levels (EQ-5D-5L), and Ulcerative Colitis Symptoms Questionnaire (UC-SQ). Results A total of, 149, 148, and, 154 pts received PBO, UPA, 15 mg, and UPA, 30 mg QD, respectively, during maintenance. At Week, 0 of the maintenance study, there were no significant differences between UPA and PBO treatment groups in the percentage of pts reporting MWPC relative to induction baseline for most pt-reported outcomes (PROs) as all pts enrolled in maintenance were UPA clinical responders during IP. For IBDQ, a significantly greater proportion of pts achieved MWPC criteria (p&lt;0.001) with UPA, 15 mg (68.9%) and UPA, 30 mg (78.6%) vs, 39.6% for PBO at Week, 52 (Figure, 1). Also, a significantly greater proportion of pts treated with either, 15 mg or, 30 mg UPA dosage vs PBO over, 52 weeks achieved MWPC for the WPAI domains (p≤0.01) of overall work improvement, presenteeism, and activity impairment (Figure, 2), in both physical and mental component summaries of SF-36 (p&lt;0.001, Figure, 3), in EQ-5D-5L (p&lt;0.001, Figure, 4), and in UC-SQ (p&lt;0.001). A numerically greater proportion of pts receiving UPA, 30 mg vs, 15 mg achieved MWPC in most PROs at Week 52. Conclusion A significantly higher percentage of pts with moderately to severely active UC who responded to UPA induction therapy maintained clinically meaningful improvements with UPA, 15 mg of, 30 mg compared to PBO consistently across a broad range of HRQOL outcomes after, 52 weeks of maintenance treatment. These HRQOL aspects include IBD symptoms (IBDQ, UC-SQ), work productivity (WPAI), physical and mental functioning (SF-36), and general well-being (IBDQ, EQ-5D).

Abstract Background Upadacitinib (UPA), a selective and reversible Janus kinase inhibitor, has been shown to be safe and effective when administered at a dose of 45 mg once daily (QD) as 8-week induction therapy in moderate-to-severe Ulcerative Colitis (UC). This analysis evaluated outcomes following extended induction (45 mg QD for 16 weeks) followed by maintenance (15 or 30 mg QD) treatment with UPA in patients with UC who did not achieve a clinical response after 8 weeks’ induction. Methods Patients with moderate-to-severe UC who failed to achieve a clinical response (Adapted Mayo score decrease of ≥2 points and ≥30% from baseline, plus ≥1-point decrease in rectal bleeding score [RBS] or absolute RBS ≤1) to 8 weeks’ induction treatment with UPA 45 mg QD in the U-ACHIEVE Induction (NCT02819635) or U-ACCOMPLISH (NCT03653026) studies, continued to receive UPA 45 mg QD in an 8-week open-label extension. Responders at the end of the open-label extension entered the U-ACHIEVE Maintenance study and were randomised 1:1 to UPA 15 mg or 30 mg QD for 52 weeks. The efficacy endpoints were evaluated at Week 16 for the induction studies and at Week 52 for the maintenance study. Results In total, 125 patients who failed to achieve a clinical response after 8 weeks’ induction treatment received open-label UPA 45 mg for a further 8 weeks. Of these patients, 48.3% achieved a clinical response at Week 16 and were re-randomised to UPA 15 or 30 mg in U-ACHIEVE Maintenance. Among 16-week responders who entered the maintenance study, clinical remission, maintenance of clinical response, and endoscopic improvement, respectively, at Week 52 were achieved in 33.3% versus 19.0%, 66.7% versus 35.7%, and 37.5% versus 23.8% of those who received UPA 30 versus UPA 15 mg QD as maintenance treatment (Table 1). Adverse events of special interest were reported infrequently in the two maintenance treatment groups (Table 2). Conclusion In this analysis, prolonged induction treatment for a total of 16 weeks was beneficial in almost half of UC patients who failed to achieve a clinical response after 8 weeks’ induction with UPA 45 mg. The benefit of maintenance therapy in these delayed responders was further demonstrated, with UPA 30 mg providing greater benefit than UPA 15 mg QD.

Abstract Background With a growing prevalence of inflammatory bowel disease (IBD) in elderly patients, there is a clinical requirement to understand the impact of treatment in this population.1 Filgotinib (FIL) is an oral Janus kinase 1 preferential inhibitor. This post hoc analysis of data collected in the phase 2b/3 SELECTION programme evaluated the efficacy and safety of FIL in patients with ulcerative colitis (UC) stratified by age. Methods The SELECTION programme includes two Induction Studies, a Maintenance Study (NCT02914522) and a long-term extension (LTE) study (NCT02914535). Adults aged 18–75 years with moderately to severely active UC were randomized 2:2:1 to receive FIL 200 mg or 100 mg or placebo once daily for 11 weeks. Responders at week 10 were re-randomized 2:1 to continue assigned FIL treatment or placebo from week 11–58. In LTE, patients with disease worsening and those completing week 58 continued assigned treatment before receiving open-label FIL. We assessed the efficacy and safety of FIL at any dose in the overall cohort of SELECTION and LTE, stratified into five age groups: &lt;30, ≥30–&lt;40, ≥40–&lt;50, ≥50–&lt;60 and ≥60 years. Clinical remission was evaluated at week 10 and pMCS remission was assessed at week 10, 58 and LTE weeks 2, 4, 12 and 24. Exposure-adjusted incidence rates (EAIRs) were calculated for adverse events (AEs). A data cut-off of 28 February 2020 was used. Results Baseline disease activity and previous and concomitant treatments were comparable across age groups in each treatment arm. While there were fewer patients in the ≥60 years group, patient distribution was similar in all other age groups. FIL induced clinical (~16%) and pMCS (~36%) remission in similar proportions of patients across all age groups at week 10 (Figure 1). At week 58, pMCS remission was achieved in ~53% of FIL-treated patients across age groups (Figure 2). In LTE, the proportion of FIL-treated patients in pMCS remission generally increased with time and remained similar across all age groups (Figure 3). FIL-treated patients aged ≥60 years had higher EAIRs of any AE, infections, herpes zoster, malignancies, NMSC and MACE than younger patients (Table). One thromboembolic event occurred in a FIL-treated patient aged &lt;30 years. Three deaths related to cardiovascular disease occurred in FIL-treated patients aged ≥50 years. Conclusion These findings suggest FIL is efficacious in inducing and maintaining symptomatic remission and could have an acceptable safety profile in adults with UC of all ages, including ≥60 years old. Age-related increases in incidences of certain AEs might be expected in patients with IBD; however, the number of patients ≥60 years limits comparison of these data with reported rates.

Abstract Background Upadacitinib (UPA), an oral, reversible JAK inhibitor engineered for increased selectivity for JAK1 over JAK2, JAK3, or tyrosine kinase 2 (TYK2), demonstrated significantly greater efficacy compared with placebo (PBO) for induction of remission in patients with moderately to severely active ulcerative colitis (UC) in two phase 3 trials, U-ACHIEVE Induction (NCT02819635) and U-ACCOMPLISH (NCT03653026). This analysis evaluated the efficacy of UPA on early symptomatic improvement for the first 14 days, using pooled data from U-ACHIEVE Induction and U-ACCOMPLISH. Methods U-ACHIEVE and U-ACCOMPLISH were multicentre, double-blind, PBO-controlled trials that enrolled patients who have had moderately to severely UC with an Adapted Mayo Score of 5 to 9 points and centrally reviewed endoscopy subscore of 2 to 3. A total of 998 patients were randomized to receive UPA 45mg once daily (QD) (n=658) or PBO (n=328) for 8 weeks (wks) in a 2:1 ratio. First dose of study drug was administered on Day 0. Improvement in symptoms including stool frequency subscore (SFS), rectal bleeding subscore (RBS), abdominal pain, and bowel urgency were analysed from daily symptom diary data. Multivariate regression analysis was used to determine if early changes in UC symptoms could be used to evaluate a potential correlation with patients’ likelihood of achieving clinical response or clinical remission per Adapted Mayo score at the end of induction. Results Baseline characteristics were similar between both treatment groups. Patients treated with UPA 45 mg QD experienced significant improvement in daily symptoms, with significantly more subjects achieving SFS≤1 (p&lt;0.001), RBS of 0 (p&lt;0.05), and SFS of 0 (p&lt;0.05) as early as day 1 and maintained through day 14 (Figure 1). A significantly higher percentage of patients who received UPA 45 mg QD compared to PBO, achieved abdominal pain=0 and the absence of bowel urgency within 3 days of beginning treatment through day 14 (p&lt;0.05). Multivariate analysis revealed that patients who achieved day 7 SFS≤1 (OR 2.42, 95% CI, 1.53–3.82) were more likely to attain clinical response (Table). Patients who attained day 7 SFS≤1 (OR 2.53, 95% CI 1.59–4.00) or day 7 bowel urgency absent (OR 2.40, 95% CI 1.52–3.79) were more likely to achieve clinical remission at week 8. Conclusion UPA 45 mg QD significantly improved UC symptoms as early as day 1, providing patients with rapid symptom relief. Patients who achieved early symptom improvement were more likely to attain clinical remission or clinical response at week 8.
